To @ZZ whom it may concern,.-

Beit known tha't I, OswALD HOFFMANN, a subject of the King of Saxony, and a resident of Neugersdori, in the Kingdom of Saxony, German Empire, have invented an Improved Yarn Skein (for which I have obtained Letters Patent in the following countries: Germany, No. 60,390, dated March 11, 1891; Austria, No. 40,320 and No. 65,216, dated December 6, 1891; France, No. 211,641, dated February 23, 1891; GreatBritain, No.5,351, dated March 25, 1891; Austria-Hungary, No. 5,161 and No. 18,194, dated July 1, 1892; Switzerland, No. 4,358, dated September 28,1891; France, No.215,220, dated July 30, 1891; Italy, No. 30,580, dated October 12, 1891; Belgium, No. 96,143, dated August 24, 1891 Spain, No. 12,521, dated September 15, 1891, and Great Britain, No. 15,563, dated September 14, 1891,) of which tbe following is an exact specification.

My invention has relation to the manufacture of banks or skeins of yarn.

IIitherto it has not been possible, when using ordinary reels, to produce skeins of yarn of suiiicient thickness to be practicably suitable for the subsequent process of dyeing, inasmuch as the variations arising in the length of the individual windings prevented the bank taking the dye uniformly throughout and also caused threads to break in the process of dyeing.

The object, therefore, of my present invention is to obviate the said disadvantages, which I attain by making every thread of a skein of the same length. Consequently it is possible by this method to produce skeins of yarn of, any desired thickness which can be employed for all practical purposes and which compared with those hitherto produced permit of increased production in the winding, as well as in the subsequent spooling or balling, and, further, greatly facilitates the process of dyeing, since my improved skein constantly preserves its uniform shape and because the threads being all of the same length they are subjected to uniform tension in the process of dyeing, and therefore breakages of thread and waste are avoided.

I refer to the accompanying drawings, in whichy i Y Figure 1 is a part sectional elevation of the reel, the said part section being taken on line A B of Fig.' 2, which latter is a" cross-sectional elevation taken on line C D of Fig. 1. Fig. 3 is an elevation of lmy improved bank 'when the banks arewound immediately next each other, and Fig. 4 isa transverse elevation of same shown on the reel. Figs. 5 and 6 show the said bank drawn out to a ringlike shape," and Fig.V 7 is a perspective view of same on a reduced scale.` In carrying out my invention I diminish the circumference of the reel used for Winding the skeins in proportion as the winding of the skein increases and in such a lmanner `that during the operation of Winding the 'their respective places, and the skein instead of being a ring of small breadth and comparatively great thickness is now a broad ring of reduced thickness. In this way the crossing of the threads likewise vary. While at first the thread is carried backward and forward over the whole Width of the skein, after the stretching of the skein the lay of the threads on the ring-like surface is such that the thread alternately touches the inner and outer circumference of the skein, Figs. 6 and 7.

The necessary contraction of the reel-lathe for `the production of said skein of yarn is brought about by the apparatus shown in Figs. 1 and 2, in which the worm-wheeld on cross-piece e rotates with the reel-shaft a by engaging with the Worm c, which .latter u iits loosely on the said reel-shaft d and is fastenedto the frame b. This sets in motion the Worm-wheel d and pin c, on which is secured a worm f, which turns the worm- Wheel g, likewise the shaft 7L, and consequently worm i and Worm-wheel Z, which 'latter is made with the bevel-wheel k. The bevel-wheels m and 7,; turn on screw-spindles n, situated radially with the reel-shaft a, and engage with each other, their bosses being arranged with screw-threads to receive the ends of the screw-spindles n, which support the reel-laths o. The said screw-spindles n screw in and out in accordance with the turning'one way or the otherof the shaft hnvhich latter is made with its end to receive a suit-- able key or crank for facilitating the turning of the said shaft after loosening the adjusting-screw` g' on the worm-Wheel g. Before beginning to reel the yarn the laths require to be placed in their normal position. The radial displacement of the laths o can be regulated by making the worm-Wheels d or g of the dimensions desired, according to the number of the yarn, which may be ascertained at any moment by measuring the circumference of theskein (which must always be uniform with skeins of any thickness) by means of a measuring-band. l

The tying of the skeins of yarn can take place in various ways. For instance, it can be done during the reeling in such a Way that after a certain quantity of yarn is reeled the tying-np cord is Wound therearound, and this is repeated until the skein is complete, so that the skein (a section of which is shown tied in this fashion at d', Fig. 3) is thus divided into several sections corresponding to the leas or numbers of the current market reelings, so the tying of the skein into sections of uniform size, as shown at d', Fig.`5, can take place after the reeling of the complete skein, the individual sections of the skein having been previously separated from each other during the reeling by bands stretched over the whole length of the reel. The ties in this case for holding the skein of yarn intact are not put on until after the skein has been successfully reeled, and thick skein or skeins of valuable yarn are then provided with several ties round them at various parts. (See U, Figs. 3 and 4.) In said Figs'- 3 and 4 the position of the cord for tying up is shown before the skein is stretched, while Figs. 5 and 6 showthe same after the skein has been stretched.

Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United States is- An improved yarn skein having the windings of yarn from the'inside to the outside of the same length, and having said windings extended from one edge of the skein tothe other so as to uniformly cross each other all over the respective layer, substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscrib-A ing witnesses.
